Make all the Equations Correct

Use any mathematical symbols on the left hand side to make all the equations correct.
However no numbers are allowed.
For eg. you can use sq root but not sq(because it is raised to the power 2, which is a number):
4 4 4 4 = 0
4 4 4 4 = 1
4 4 4 4 = 2
4 4 4 4 = 3
4 4 4 4 = 4
4 4 4 4 = 5
4 4 4 4 = 6
4 4 4 4 = 7
4 4 4 4 = 8
4 4 4 4 = 9
4 4 4 4 = 10
4 4 4 4 = 11
4 4 4 4 = 12
4 4 4 4 = 13
4 4 4 4 = 14
4 4 4 4 = 15
4 4 4 4 = 16
4 4 4 4 = 17
4 4 4 4 = 18
4 4 4 4 = 19
4 4 4 4 = 20
4 4 4 4 = 21
4 4 4 4 = 22
4 4 4 4 = 23
4 4 4 4 = 24
4 4 4 4 = 25
4 4 4 4 = 26
4 4 4 4 = 27
4 4 4 4 = 28
4 4 4 4 = 29
4 4 4 4 = 30

1) 4-4+4-4=0
2) (4/4)*(4/4)=1
3) (4/4)+(4/4)=2
4) ((4*4)-4)/4=3
5) (Root 4 + Root 4 + Root 4) - Root 4=4
6) (Root 4 + Root4)+ (4/4)=5
7) (Root 4 * Root 4 * Root 4) - Root 4=6
8) (4+4)-(4/4)=7
9) (4+4)*(4/4)=8
10) (4+4)+(4/4)=9
11) (Root 4 * Root 4 * Root 4) + Root 4=10
Rest I will leave upon you to Solve. Answer in Comments.
